Description

Technical Field

[0001] The invention relates to the technical field of mold inspection equipment, in particular to a flip-type automobile metal mold inspection device. Background Art

[0002] Automotive metal molds are a general term for molds used to manufacture all metal parts on cars, including stamping molds, injection molds, forging molds, casting wax molds, glass molds, etc. The design and manufacturing technology of automotive molds are directly related to the quality and market competitiveness of the car. Automotive metal molds need to be inspected before leaving the factory to promptly discover potential problems and defects in the molds, avoid the production of unqualified products, ensure that the quality and performance of the molds meet the design requirements and customer standards, and improve product quality. At present, an inspection device is required to inspect automotive metal molds. The inspection device can detect defects on the surface of automotive metal molds through visual inspection technology, such as a detection device for automotive mold inserts with prior art publication number CN219777507U.

[0003] However, the current existing technology requires multiple cameras to conduct a comprehensive inspection of the mold, which is costly. In addition, in order to fully inspect the automobile metal mold, the automobile metal mold needs to be flipped over. Due to the different shapes of the mold's exterior, the height of its top changes during the flipping process (for example, a rectangular mold, its horizontal height is inconsistent with its height after flipping 90°). Therefore, in the existing technology, if the top of the mold exceeds the height of the third camera during the flipping process, the mold is prone to collide with the camera of fixed height, causing damage to the camera. Although the camera can be set high enough, if the camera is too far away from the mold, it is easy to affect the shooting effect and affect the inspection effect. Summary of the invention

The visual inspection camera 61 can realize a comprehensive shooting inspection of the automobile metal mold 5.

[0049] Next, in order to improve the fixing stability of the automobile metal mold 5, as Figure 3-8 As shown, specifically, the upper fixing mechanism 6 also includes an elastic telescopic rod 1 63 fixedly arranged at the top of the visual inspection camera 61 and an upper arc plate 62 arranged at the bottom of the visual inspection camera 61, and the upper arc plate 62 is in contact with the top of the automobile metal mold 5; a lower fixing mechanism 7 is also provided at the bottom of the automobile metal mold 5, and the lower fixing mechanism 7 includes a lower arc plate 71 and an elastic telescopic rod 2 72 fixedly arranged at the bottom end of the lower arc plate 71, and the elastic telescopic rod 2 72 is fixed at the top of the inspection table 2, and the lower arc plate 71 is in contact with the bottom end of the automobile metal mold 5;

[0050] Furthermore, the elastic telescopic rod 2 72 has the same structure as the elastic telescopic rod 1 63. The elastic telescopic rod 1 63 includes a square outer rod 631, a square inner rod 632 and a spring 633. The square inner rod 632 is arranged inside the square outer rod 631 and extends out of an end of the square outer rod 631 close to the automobile metal mold 5. An end of the square inner rod 632 away from the automobile metal mold 5 is connected to the inner wall of the square outer rod 631 through the spring 633.

[0051] The upper arc plate 62 is mirror-symmetrical to the lower arc plate 71 , the raised arc surfaces of the upper arc plate 62 and the lower arc plate 71 are in contact with the automobile metal mold 5 , and the recessed arc surface of the lower arc plate 71 is fixed to the square inner rod 632 on the elastic telescopic rod 2 72 .

[0052] The steps of inspecting the automobile metal mold 5 of the present invention are as follows:

[0053] Step 1: The feeding manipulator 14 places the automobile metal mold 5 to be inspected on the feeding conveyor 11 in the space between the two clamping plates 43, the upper arc plate 62 and the lower arc plate 71 on the inspection table 2. At this time, the automobile metal mold 5 is placed on the lower arc plate 71, and the gravity of the automobile metal mold 5 presses down the lower arc plate 71, so that the spring 633 on the elastic telescopic rod 2 72 is compressed, and then the visual inspection camera 61 on the upper fixing mechanism 6 is adjusted to the appropriate position on the top of the automobile metal mold 5 by using the Y-axis linear module 8 and the X-axis linear module 9, and then the Z-axis hydraulic cylinder 10 is extended. The upper fixing mechanism 6 is driven to move downward, so that the upper arc plate 62 contacts the top of the automobile metal mold 5, and then the Z-axis hydraulic cylinder 10 continues to extend to compress the spring 633 on the elastic telescopic rod 1 63, until the visual inspection camera 61 has a suitable height from the automobile metal mold 5 (when using a camera to shoot, in order to obtain a clear image, the distance from the camera lens to the object should be much greater than twice the focal length of the lens), and then the electric push rod 42 drives the clamping plate 43 to move to clamp the front and rear sides of the automobile metal mold 5. At this time, the automobile metal mold 5 is clamped and fixed in the front, back, up and down directions, and has high stability;

[0054] Step 2: During inspection, the Y-axis linear module 8 drives the visual inspection camera 61 to move forward and backward. At this time, the fixing block 64 drives the connecting rod 65 to move forward and backward along the slide rail 66. The visual inspection camera 61 takes a picture of one side of the automobile metal mold 5, and the image is transmitted to the computer of the inspection device for analysis and inspection;

[0055] Step 3: After one side of the automobile metal mold 5 is photographed, the motor in the motor mounting seat 44 drives the electric push rod 42 to rotate, driving the automobile metal mold 5 to flip to the other side in the vertical direction. During the flipping process of the automobile metal mold 5, since the spring 633 has a compression amount, when the height of the top and bottom ends of the automobile metal mold 5 changes, the automobile metal mold 5 pushes the upper arc plate 62 and the lower arc plate 71 outward to move downward, as shown in FIG. Fig. 9 As shown, there will be no collision accident of the automobile metal mold 5, and at the same time, the upper arc plate 62 and the lower arc plate 71 are still clamped and fixed to the automobile metal mold 5 under the elastic force of the spring 633, and the automobile metal mold 5 has high stability;

[0056] At the same time, the upper arc plate 62 moves upward to drive the visual inspection camera 61 to move upward. At this time, the distance between the top of the automobile metal mold 5 and the visual inspection camera 61 does not change, avoiding the need to refocus due to the change in the distance between the lens of the visual inspection camera 61 and the automobile metal mold 5, thereby ensuring the clarity of the shooting;

[0057] Step 4: The motor in the frame 1 drives the turntable 3 to rotate in the horizontal direction, and the turntable 3 is driven to rotate through the transmission of the driving gear 32 and the inner gear ring 31, thereby driving the flip fixture 4 to rotate and drive the automobile metal mold 5 to flip in the horizontal direction. Fig.10 As shown;

[0058] Step 5: After the automobile metal mold 5 is turned over, the visual inspection camera 61 continues to photograph and inspect the other surfaces of the automobile metal mold 5 until the comprehensive inspection of the automobile metal mold 5 is completed;

[0059] Step 6: After the inspection is completed, the flip clamp 4 is released, and the discharging robot 15 takes out the inspected automobile metal mold 5. The qualified automobile metal mold 5 is placed on the qualified product discharging conveyor 12 and transported to the next workstation, and the unqualified automobile metal mold 5 is placed on the unqualified product discharging conveyor 13 and transported to other workstations.
